Abstract

We describe a new method that permits the simultaneous measurement of the nonlinear refractive index n⁽²⁾ and the nonlinear absorption or gain coefficient α⁽²⁾ The method also permits separate measurement of the fast, electronic n⁽²⁾ and the slow thermal n⁽²⁾ Furthermore, the four-wave-mixing coefficient X can be measured with only a slight modification in the experimental setup.
